Title: Magneto-optical recording medium
Inventor: TANASE KENJI
IPC: G11B11/10
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical recording medium in which each magnetic domain of a recording layer is accurately transferred to a reproducing layer even at a high recording density and in which the transferred magnetic domain can be detected. SOLUTION: The magneto-optical recording medium 10 has a light transmissive substrate 1, an underlayer 2, a reproducing layer 3, a 1st mask layer 4, a nonmagnetic layer 5, a 2nd mask layer 6, a recording layer 7 and a protective layer 8. The reproducing layer 3 is a magnetic layer that changes from an longitudinally magnetized film to a perpendicularly magnetized film at a prescribed temperature or above. The 1st mask layer 4 is an longitudinally magnetized film at room temperature and loses its magnetization at the prescribed temperature or above. The 2nd mask layer 6 is a magnetic layer that changes from an longitudinally magnetized film to a perpendicularly magnetized film at the prescribed temperature or above.  When the length of a region of the 1st mask layer 4 in which the magnetization vanishes is made nearly equal to the shortest domain length of the recording layer 7, each magnetic domain of the recording layer 7 is transferred to the reproducing layer 3 by way of only the region of the 1st mask layer 4 in which the magnetization has vanished.

Title: Clamp circuit
Inventor: OHASHI SHINICHI
IPC: H04N5/18
Filed: 1988-04-18
Abstract: PURPOSE:To prevent the disturbance of a picture due to level fluctuation of a video signal by using a conduction current obtained through the application of a video signal to a series circuit comprising the 2nd capacitor and a rectifier element as a drive signal for a switching element. CONSTITUTION:In the application of the video signal to a series circuit comprising the 2nd capacitor 8 and a rectifier element 10, a conductive current flows to the element 10. The conduction current flows synchronously with the synchronizing signal. Thus, in the case of driving a transistor(TR) 7 by using the conduction current, a peak clamp circuit comprising the 1st capacitor 6 and the TR 7 is clamped at the location of the synchronizing signal even if the video signal level is lowered. Thus, the disturbance in the picture caused by missing of the synchronizing signal due to level fluctuation of the video signal caused by invasion of a ghost signal or the like is prevented.

Title: Program executing device
Inventor: ANDO ATSUSHI
IPC: G06F9/45
Filed: 1989-04-13
Abstract: PURPOSE:To compile and execute a program, in which a program and data are described in a language in the same syntax, without requiring a module having all functions regulated by means of language specifications by providing a linkage editing part, etc. CONSTITUTION:When the program, which is newly generated by the operation of the data, is executed during the execution of a program code, the program is processed by a program executing part 106. In such a case, the executing part 106 checks whether or not the module necessary for the function utilized in the process of the processing is present in the program code at such a time with the use of a function table 104 in a storing part 105. As a result, when the module is not present, a linkage editing part 108 searches a library 107 for the necessary module, links it to the program code during the execution, and after a flag is set in the table 104, the module function is utilized. Thus the module having the all functions regulated by the language specifications is not required, and the program, in which the program and the data are described in the language in the same syntax, can be complied and executed.

Title: Production of in-mold foamed molded object of polypropylene resin
Inventor: MAEDA HIROFUMI
IPC: C08J9/228
Filed: 1996-03-22
Abstract: PURPOSE: To produce an in-mold foamed molded object made of polypropylene excellent in fusion rate and surface appearance by regulating the peak quantity of heat of fusion based on an m.p. on a high temp. side to a specific range and filling mold with compressed prefoamed particles by a specific filling method and regulating the compression rate of the prefoamed particles to a specific range. CONSTITUTION: The quantity QH of heat of fusion of prefoamed particles of a polypropylene resin is 0.3-3.5cal/g, pref., 0.5-3.0cal/g and, when the quantity of heat of fusion is below 0.3cal/g, the dimensional shrinkage (sink) of a molded object becomes large. Prefoamed particles are charged in a pressure-resistant container 12 to be compressed by gas pressure. Subsequently, the preformed particles are charged in a mold 3 capable of being closed but not hermetically sealed and excessive gas is vented from the mold 3. At this time, the compression rate of the prefoamed particles is set to a range of 10-60%. The mold is uniformly filled with the prefoamed particles compressed in such a state that the pressure-resistant container 12 compressing the prefoamed particles and the mold 3 become almost same in pressure.

Title: Manufacture of laminated board
Inventor: HORIBATA SOICHI
IPC: C08J5/24
Filed: 1991-04-24
Abstract: PURPOSE:To reduce the occurrence of smear defects in a laminated board and manufacture laminated boards with excellent productivity, moreover, high thick ness accuracy, to thereby decrease the warpage deformation of the laminated board. CONSTITUTION:Continuous base materials 1 are impregnated with polybenzimidazole resin 2 and while being forwarded, a plurality of sheets thereof are put on one another and still continuous metallic foils 3 are superimposed thereon. While being forwarded continuously, this is heated under non-pressure for solidifying and integrally laminating the polybenzimidazole resin 2 and after being cut into a predetermined length, it is re-heated so as to obtain a laminated board A. Polybenzimidazole has a high deformation temperature and therefore the occurrence of smears is small. Because of the continuous method, the productivity becomes high and the laminated board A is lamination- molded one by one, thus the scatter of board thickness between respective laminated boards becomes small. By re-heating after thermally curing the polybenzimidzole resin, the warpage deformation of the laminated board can be decreased.

Title: Differentiation type squid
Inventor: NAITOU SEIICHI
IPC: H01L39/22
Filed: 1982-06-01
Abstract: PURPOSE:To miniaturize the entire body and thus perform the local detection of magnetic field signal with good accuracy, by forming a pickup coil for magnetic flux detection and a SQUID ring in a common structure. CONSTITUTION:At the part of intersections of lead electrodes 31 and 32, a part of an insulation layer 4 is in the state of conduction, and this conductor part JC forms a cubic Josephson junction part. When a differentiation type SQUID rf SQUID is placed in a uniform magnetic flux phix from a distance, a shielding current (i) flows into ring superconductive films 21 and 22 to keep the magnetic flux in a superconduction closed loop 21 and 22 constant. The currents flowing into the lead electrodes 31 and 32 become the same, and then current does not flow into the Josephson junction part JC. To the magnetic flux having gradient from the neighborhood, different shielding currents flow into the ring superconductive thin films 21 and 22; the current corresponding to the flux gradient flows into the Josephson junction part JC, and accordingly the signal can be taken out.

Title: Ignition device for internal combustion engine
Inventor: UMETSU KAZUHISA
IPC: F02P11/02
Filed: 1988-04-14
Abstract: PURPOSE:To prevent the occurrence of kicking back during kick-starting, by a method wherein a power source for an ignition signal generating circuit to output an ignition signal based on an output signal from a signal coil is generated by means of an output from a generating coil through the short-circuit motion of a constant voltage circuit. CONSTITUTION:When a crank shaft is rotated by kick-starting, a generating voltage is outputted from a generating coil 1 to charge capacitor 2 and 3. An ignition signal is fed from a signal coil 9 in linkage with running of a engine, but in this case, when the number of revolutions of an engine is below a given value, since the charge voltage of the capacitor 3 is below the set voltage of a constant voltage circuit 31, a thyristor 32 is not energized. Since a power source is not fed to a one shot circuit 28, no ignition signal is generated from an ignition signal generating circuit 13. Meanwhile, when the number of revolutions of an engine exceeds a given value, the thyristor 32 is energized, an ignition signal is generated from the ignition signal generating circuit 13, and an ignition motion is effected.

IPC: B41M5/34
Filed: 1986-04-23
Abstract: PURPOSE:To achieve color printing through single printing operation by laminating yellow, magenta, cyan and/or black ink onto an ink ribbon in the direction of the thickness thereof. CONSTITUTION:Color inks yellow 5, magenta 6, cyan 7 and black 8 are laminat ed onto the base 13 of a ribbon 15. Since a combination of two colors is required, one primary color is composed of double layers where the primary inks are made different in the fusing temperature and the color is selected by the thermal temperature produced from a head 4 or ribbon base 13. When the melting points of yellow 5, magenta 6, cyan 7 and black 8 and yellow 9 are 60 deg.C, 80 deg.C, 100 deg.C, 140 deg.C and 120 deg.C, respectively, only yellow 5 fuses to adhere to a recording paper 1 if the heat producing temperature is 70 deg.C while yellow 5, magenta 6 and cyan 7 fuse for the heat producing temperature of 110 deg.C and the uppermost color cyan 7 is recognized. In case of a combination color of two primary colors, yellow 5 fuses completely when the temperature of 80-odd deg.C is produced and mixed with a portion of adjoining magenta 6, whereby mixed red color 16 adheres to a recording paper 1.

Title: Screw press dehydrator
Inventor: FUKUI HARUO
IPC: B30B9/16
Filed: 1983-05-27
Abstract: PURPOSE:To provide a screw press dehydrator with which dehydrated cake contg. uniform and low moisture is obtd. by consisting the same of the 1st screw on a sludge feed port side which delivers sludge to a cake discharge port while dehydrating the same and the 2nd screw which is reversed in the winding and rotating direction of screw vanes. CONSTITUTION:The sludge conveyed by a screw 7 is deposited in the part where there are no vanes. The sludge is compacted by the difference in the rotating speeds of both screws 7 and 9 then the sludge is exactly filled between the screw vanes 16 and 16 of the succeeding 2nd screw 9. The winding and rotating directions of the screw vanes 15, 16 are reversed with the screws 7 and 9 and therefore the direction where the cake is transferred by the screw 7 is V1 while said direction is inverted to V2 by the screw 9. The sludge is therefore strongly forced between the vanes 16 and 16. The sludge is compacted by the above-mentioned difference in the transfer speeds in the juncture of the screw shafts 8, 10 having no vanes so that the sludge existing on the front surface of the vane 6 and the rear surface of the vane 16 is provided similarly and exactly with the compaction effect and is dehydrated. The sludge is further dehydrated by the torsional effect and strong shearing effect applied thereon by the directional change of the sludge arising when the sludge is transferred to the screw 9.
